WITNESSES A TTORNE Y 8 v device for which application was filedby ne fini fivnx nve mncnn Be it known that I, wamwneisa, ajeitizen of the UnitedStates, and a'resideflnt of the city of New York, borough of Ma'nhattan, 1n the county and State otNew York, have invented a newand ImprovedMixing Faucet, of which the following {is a full, 1 clear, and exactdescription. I I s liquid mixing This invention relates to means, andhas reference more' particularly to means for mixing hot and cold water,said means being controlled byfa hand ,lever' so that the water issuesfrom the iaueetfatthede 1 sired temperature. This application ,furtherrelates to and is an improvement. over the June 19, 1919', serial Numbereoezcmnd is also an improvement over the device shown in applicationfiled October 25, 1919; Serial Number-333151. l 1

An object of. this inventi i is ol'provide a hand controlledmixingfaueetlinkwhich the flow and temperatureloyf the. water 'i'ssu? e!c miat y 9 .5 7 i i similarly-suspended between the otheripairf c fromthe faucet can. trolled by a lever. H y I 4 v i i 1 Another object ofthis invention is toprovide a mixing faucet which canioejeasily di'sassembled so that repairs'can' be made."

A further object lofthis inventionzfisto provide a mixing faucet whichhaslval ves of resilientmaterial, said' valvjes being provided withmeans for adjustment when necessary due "to wear.

A still further object of this invention is to provide a mixing faucetwhich is espe: cially adapted for useon sinks, shower baths,

and the like.

The stuflinghoxv 13Islidaloly engages a"control rod 14 sothatsaid rod is positioned coaxial-j with i the chamber10; 1 An annular shoulder 15 is provided on thfe {rod 14 which a isadapted to engage an annular recess in the f {cap 312 so that axialmovementof'the rod 145 is prevented. 1A lever 16 :is secured toktheupper, end of thendie loy means ofhpin 17 so that said rod may berotated by said lever.

that as said rod 14' is ;rot ated by means of the V lever 16 the collar.28 will be'movedaxially alongsaid rod. 1 The collar 28fis provided with"diametrically opposite outstanding flanges 30;;and'a laterallyextendingpin 31 e is securedrto a; the QIIClO f OIIGQOf the flanges 30.so as to engagethecam slot123, and a -Jlatra1ly extending pinu32 issecuredto thef uendlof the other fiange'fio, so as toengage-the cam slot24:. "The pins 31 and 32 serveto f a k I a up v I f move' thecal'nblocksl9 andj21 about their a fragmentary sectional view of one oftheimproved adjustable valves.

pivots when 'thecollar 28 is moved vertically provided in .thegwall ofthe chamber 10 ad-v is formed the cam block 21. Each of the ports 33 and34has a threaded section 35 to which is secured water pipes 36 and 37which may be curved, straight, or provided with unions 38 connectingsaid pipes to service, pipes 39, passing through the wall 40 of thesink, the axis of said service pipes 39 being preferably at right anglesto the axis of the pipe '11 so that the water or other liquid is directed downwardly. The pipe 37 may supply cold water and the pipe 36hot'water,-or

vice versa. 7 I

A valve stem 41 is pivoted at one end to the lower end of the block 19by means of a pin 42, and a valve stem 43 is pivoted to the lower end ofthe cam block 21 by a pm 44. Each of the valve stems 41 and 43 is pro- Ivided with a threadedsection 45 which forms shoulders 46 with-thevalvestems 41 and 43. Frusto-conical resilient valve 'washers 47 and 48 aremounted coaxially on sections 45, the smaller ends of said washer beingadapted to-engage valve seats 50 formed on-each of the ports 33 and 34when the valve is in aclosed position. Each of the Washers 47 and 48 ispreferably madeof a soft material such as rubber and is held in place bya semi-spherical metal washer 51 held in place by a nut 52. r Thecontact surface 53 of each of the washers 47 and 48 with the valve seats50 is preferably semi-spherical in shape 7 so that as the valve'washersbecome worn they'maybe'adjusted by tightening nuts 52 so that thesurfaces 53 are flattened out and approach theirrespective valve seatsmore closely. a

In the modification shown in Figure 5, the

outlet pipe '11,, may be formed" on the wall of the chamber 10 and maybe connected to a pipe 54 which leads to ya 'showerbath or any otherdesired device.

Inoperation, when the lever 16 isin thev extreme position shown inFigure 4, the pins 31 and 32 will engage the cam slots 23 and 24 so thatthe cam blocks19 and 21, pull the valve washers tightly against thevalve seats 50 so that no *water flows into the mixing chamber 10through the pipes 36 and 37., As the lever 16 is slowly rotated in aclock Wise direction, the collar 28 moves downwardly, thus causing thepin 32 to loosen but not unseat the valve Washer 48 while the pin 31opens the valve 47. 'At the position shown in Figure 1, valve 47 isfully opened and the valve 48 is still closed, and upon a continuedclock wise rotation of the lever; 16, the valve '47 will slowly closewhile the valve 48 opens until the proper'temperature and flow of waterfrom the pipell is obtained. Thus a thorough mixing of hot'and coldwater from the pipes 36 and 37 is obtained in the I would state inconclusion that while the illustrated example constitutes .a practicalembodlment of my invention, I do not'limit myself strictly to themechanical details herein illustrated, since manifestly the same canbeconsiderably varied without departure from the spirit of the inventionasdefined in the appended claims.

Having thus described my invention, I claim as new and desire to secureby Letters Patent: T
